Texas Instruments UCC27332-Q1 Single Channel High-Speed Low-Side Gate Driver can effectively drive MOSFET and GaN power switches. UCC27332-Q1 has a typical peak drive strength of 9A, which reduces the rise and fall times of the power switches, lowering switching losses and increasing efficiency. The UCC27332-Q1 device’s small propagation delay yields better power stage efficiency by improving the dead time optimization, control loop response, pulse width utilization, and transient performance of the system.
The Texas Instruments UCC27332-Q1 can handle –5V on its input, which improves robustness in systems with moderate ground bouncing. An independent enable signal allows the power stage to be controlled independently of the main control logic. The gate driver can quickly shut off the power stage if there is a fault in the system (which requires the power train to be turned off). The enable function also improves system robustness. Many high-frequency switching power supplies exhibit high-frequency noise at the gate of the power device, which can get injected into the output pin of the gate driver and cause the driver to malfunction. The UCC27332-Q1 performs well in such conditions due to its transient reverse current and voltage capability.
